The article calculates and justifies the annual economic efficiency of implementing the results obtained from improving the design of the supply cylinder in 1344 spinning chambers of 3 BD-448 machines.
The economic efficiency of introducing high-performance spinning machines into production, ensuring the production of high-quality products, was calculated based on the current "Methodology for determining economic efficiency of introducing new equipment, innovations and rationalization proposals into the national economy".
Annual economic efficiency was calculated by comparing the variable costs of the basic and proposed technological options according to this methodology [1, 2, 3].
The frequency of rotation of the chambers in the BD-448 spinning machine is 100,000 min-1. In order to evaluate the role of the newly recommended supply cylinder in the spinning technology process and the results obtained in the BD-448 spinning machine, a carded yarn with a linear density of 29 tex was processed from the BD-448 pneumatic spinning machine. A wick of Bukhara-102 cotton fiber of the 4th type, 1st grade, good class was used for yarn production. The recommended feeding cylinder in this spinning machine reduces damage to the fiber roving and delivers it to the discretization zone without disturbing its smooth parallel stable movement along its width and length, as a result of which the number of yarn breaks is reduced, its quality is increased, and economic efficiency is achieved.
According to the current methodology, the economic efficiency obtained in the production
and use of a new labor tool (machine, equipment, etc.) is calculated by the following formula [4, 5, 6]:

equipment; H{, M2> - annual operating costs of the consumer using the base and new equipment in the implemented option.
The cost-effectiveness of this research work is based on cash flow covering all costs associated with purchasing, transporting, installing, and operating the equipment. [7, 8, 9, 10, 11, 12, 13, 14].
